EFFECT OF TEMPERATURE AND STRAIN UPON SHIP STEELS

The effects of flame straightening and both hot and cold forming upon material properties of hot rolled, normalized, and quenched and tempered steels were investigated. Flame straightening was studied by first simulating the effects of time at temperature upon the tensile and impact properties of seven steels. Straightening was then performed within the determined limits upon 4-foot-square plates which had been distorted by welding them into a rigid frame. As a result of these studies, it is recommended that flame straightening with appropriate controls be allowed as an acceptable process for distortion removal for both normalized and quenched and tempered steels. Simulations of outer fiber strain resulting from both hot and cold forming were conducted to determine the effects of temperature and strain upon properties. In general, it was found that either tensile or impact properties were reduced to some degree by most operations.
